具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合本发明具体实施例及相应的附图对本发明技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
以下结合附图，详细说明本发明各个实施例公开的技术方案。
请参考图1～图5，本发明实施例公开一种振动装置，所公开的振动装置可应用于电子设备。本发明实施例公开的振动装置包括支架100、导向轴200、振子300、第一 电磁线圈、第二电磁线圈、第一永磁体和第二永磁体。
支架100为振动装置的基础构件，支架100能够为振动装置的其它部分提供安装基础。在本发明实施例中，导向轴200设置于支架100，具体的，导向轴200固定于支架100。振子300转动地设置于导向轴200，且可沿导向轴200移动，振子300沿导向轴200移动，进而能够实现第一模式下的振动。振子300绕导向轴200转动，进而能够实现第二模式下的振动。
在本发明实施例中，第一永磁体和第二永磁体均设置于振子300上。第一电磁线圈和第二电磁线圈均设置于支架100。第一永磁体用于与第一电磁线圈配合，第二永磁体用于与第二电磁线圈配合。
在第一电磁线圈通电，且第二电磁线圈断电的情况下，第一电磁线圈通过与第一永磁体的配合，驱动振子300沿导向轴200往复移动。在此种情况下，第二电磁线圈处于断电状态，因此不会对第一电磁线圈与第一永磁体的配合产生影响，第一电磁线圈通电产生的磁场(交变磁场)会对第一永磁体产生磁力，进而使得第一永磁体带动振子300沿导向轴200往复移动，最终实现整个振动装置在第一模式下的振动。
在第一电磁线圈断电，且第二电磁线圈通电的情况下，第二电磁线圈通过与第二永磁体的配合，驱动振子300绕导向轴200转动。在此种情况下，第一电磁线圈处于断电状态，因此不会对第二电磁线圈与第二永磁体的配合产生影响，第二电磁线圈通电产生的磁场(交变磁场)会对第二永磁体产生磁力，进而使得第二永磁体带动振子300绕导向轴200转动，进而实现整个振动装置在第二模式下的振动。需要说明的是，本发明实施例中，振动装置在第一模式下的振动方向与在第二模式下的振动方向不同。
本发明实施例公开的振动装置中，通过将第一永磁体和第二永磁体设置于振子300上，通过控制第一电磁线圈和第二电磁线圈的通断电，进而能够分别实现对第一永磁体和第二永磁体的驱动，进而能够在一种状态下使得第一永磁体带动振子300实现第一模式的振动以及在另一种状态下使得第二永磁体带动振子300实现第二模式的振动。可见，本发明实施例公开的振动装置能够实现不同方向上的振动，在电子设备被放置在口袋中或电子设备贴着人体等特定场景下，采用此振动装置的电子设备能够实现更多方向的振动，进而能够提高电子设备的振动提示效果。
支架100为振动装置的基础构件，支架100的结构可以有多种，可选的方案中，支架100具有内腔100a，导向轴200固定安装于支架100，且至少部分位于内腔100a中，振子300、第一电磁线圈、第二电磁线圈、第一永磁体和第二永磁体均设置于内腔100a中，从而能够被支架100防护。当然，此种装配结构使得振动装置的大部分构件或一些构件的大部分结构能够位于内腔100a中，进而有利于振动装置的模块化设计。
在具体的工作过程中，第一电磁线圈和第二电磁线圈需要通电，基于此，本发明实施例公开的振动装置还可以包括柔性导线或柔性电路板，柔性导线或柔性电路板可以一部分固定在内腔100a中，并与第一电磁线圈或第二电磁线圈电连接，柔性导线或柔性电路板的另一部分可以伸出内腔100a之外，从而与电子设备的电源侧电连接。具体的，柔性导线或柔性电路板的另一部分可以通过开设于支架100的穿孔伸出内腔100a之外。
一种具体的实施方式中，支架100可以包括中框110、第一盖体120和第二盖体130，第一盖体120和第二盖体130分别固定在中框110相背的两个端口。具体的，第一盖体120和第二盖体130可以分别通过焊接、粘接等方式固定在中框110相背的两个端口。第一盖体120、第二盖体130和中框110围成内腔100a。具体的，第一盖体120和第二盖体130还可以可拆卸地安装于中框110相背的两个端口，在此种情况下，第一盖体120和第二盖体130能够拆卸，进而方便对内腔100a内的构件进行维修或更换。
请再次参考图1，在本发明实施例中，内腔100a可以包括顶壁100a1、底壁100a2和侧壁100a3，顶壁100a1和底壁100a2相对设置，且侧壁100a3位于顶壁100a1与底壁100a2之间。导向轴200的一端固定于顶壁100a1，导向轴200的另一端固定于底壁100a2。此种情况下，导向轴200以支架100为安装基础，有利于提高振子300绕导向轴200转动的稳定性。具体的，顶壁100a1可以为第一盖体120的内侧表面，底壁100a2可以为第二盖体130的内侧表面，侧壁100a3可以为中框110的内侧表面。
具体的，顶壁100a1可以开设有第一安装孔，底壁100a2可以开设有第二安装孔，导向轴200的一端可以通过焊接、过盈配合等方式固定在第一安装孔内，导向轴200的另一端也可以通过焊接、过盈配合等方式固定在第二安装孔内。
在本发明实施例中，第一电磁线圈和第二电磁线圈均设置于支架100，第一电磁线圈和第二电磁线圈的结构可以有多种。例如，第一电磁线圈和第二电磁线圈可以为整体式结构，也可以为分体式结构，同理，第一永磁体和第二永磁体可以为整体式结构，也可以为分体式结构。请再次参考图1，一种可选的方案中，第一电磁线圈可以包括第一子线圈410和第二子线圈420，第一子线圈410设置于顶壁100a1，第二子线圈420设置于底壁100a2，相应地，第一永磁体可以包括设置在振子300上的第一子磁体610和第二子磁体620，第一子磁体610设置于振子300朝向顶壁100a1的一端，且与第一子线圈410相对设置，从而能够使得第一子磁体610与第一子线圈410配合。第二子磁体620设置在振子300朝向底壁100a2的一端，且与第二子线圈420相对设置。在具体的工作过程中，第一子线圈410和第二子线圈420的通电电流方向调整，以驱动振子300沿导向轴200往复移动。第一子线圈410与第一子磁体610以及第二子线圈420与第二子磁体620中一者实现磁性相吸，另一者实现磁性相斥，从而通过协同作用实现振子300进行往复移动。
在上述具体结构的情况下，下面结合附图详细说明振动装置在第一模式下的振动过程，请参考图1，在第一子线圈410和第二子线圈420通电方向为第一方向时，第一子线圈410与第一子磁体610磁性相斥，第二子线圈420与第二子磁体620磁性相吸，在此种情况下，振子300在第一子磁体610和第二子磁体620的带动下朝向箭头A的方向移动。请参考图2，在第一子线圈410和第二子线圈420的通电方向为第二方向时，第一子线圈410与第一子磁体610磁性相吸，第二子线圈420与第二子磁体620磁性相斥，在此种情况下，振子300在第一子磁体610和第二子磁体620的带动下朝向箭头B的方向移动，在具体的工作过程中，通过第一子线圈410和第二子线圈420的通电方向的变化，进而实现振子300在箭头A和箭头B的方向交替移动，达到往复移动的目的。具体的，第一方向与第二方向相反。
一种可选的方案中，请参考图3，在第一子线圈410的通电方向和第二子线圈420的通电方向不同时，第一子线圈410与第一子磁体610磁性相吸，第二子线圈420与第二子磁体620磁性相吸，在此种情况下，振子300能够停止移动，进而实现振动的停止。在本发明实施例中，第一子线圈410和第二子线圈420均通有交变电流。
上述可选的方案，使得第一电磁线圈包括第一子线圈410和第二子线圈420以及使得第一永磁体包括第一子磁体610和第二子磁体620，从而有利于第一电磁线圈和第一永磁体在支架100上的布局更加合理，同时能够使得第一电磁线圈和第一永磁体在支架100上的设置更加灵活，从而使得振动装置的质量更加均衡，有利于提高振动的稳定性。
具体的，第一子线圈410可以为第一环状线圈绕组，第一环状线圈绕组可以围绕导向轴200设置。第一子磁体610可以绕导向轴200设置。在此种情况下，第一子线圈410和第一子磁体610均为环状结构件，有利于第一子线圈410与第一子磁体610之间施加作用力，从而使得振子300实现更均衡的振动，避免由于受力不均而产生的偏振现象。
同理，第二子线圈420可以为第二环状线圈绕组，第二环状线圈绕组可以围绕导向轴200设置，第二子磁体620可以绕导向轴200设置。在此种情况下，第二子线圈420和第二子磁体620均为环状结构件，有利于第二子线圈420和第二子磁体620之间施加作用力，从而使得振子300实现更均衡的振动，避免由于受力不均而产生的偏振现象。
为了方便安装，第一子线圈410可以固定在第一盖体120的内侧表面，进而能够随同第一盖体120在中框110上的安装而实现安装。同理，第二子线圈420可以固定在第二盖体130的内侧表面，进而能够随同第二盖体130在中框110上的安装而实现安装。
可选的方案中，第二电磁线圈可以包括第三子线圈510和第四子线圈520，侧壁100a3可以包括第一区域和第二区域。第一区域与第二区域可以相对设置，第三子线圈510设置在第一区域，第四子线圈520设置在第二区域，第二永磁体包括间隔设置在振子300上的第三子磁体710和第四子磁体720，第三子磁体710与第三子线圈510相对设置，第四子磁体720与第四子线圈520相对设置。
在具体的工作过程中，请参考图4，在第三子线圈510和第四子线圈520的通电方向为第三方向时，第三子线圈510与第三子磁体710磁性相斥，与此同时，第四子线圈520与第四子磁体720磁性相吸，从而驱动振子300在一个方向转动。请参考图5，在第三子线圈510和第四子线圈520的通电方向为第四方向时，第三子线圈510与第三子磁体710磁性相斥，与此同时，第四子线圈520和第四子磁体720磁性相斥，从而驱动振子300在另一个方向转动，最终通过控制第三子线圈510和第四子线圈520的通电方向来控制振子300实现往复转动，进而实现振动装置在第二模式下的振动。具体的，第三方向与第四方向相反。
在本发明实施例中，侧壁100a3可以开设有第一安装空间和第二安装空间，第三子线圈510可以固定在第一安装空间内，例如，第三子线圈510通过粘接、卡接的方式固定在第一安装空间内。第四子线圈520可以固定在第二安装空间内，例如，第四 子线圈520可以通过粘接、卡接的方式固定在第二安装空间内。在本发明实施例中，第一安装空间和第二安装空间可以是开设于侧壁100a3的安装槽或安装孔。上述设置第三子线圈510和第四子线圈520的方式能够减小第三子线圈510和第四子线圈520在内腔100a中的占用空间。
为了提高转动的稳定性，第三子磁体710和第四子磁体720可以对称地设置在振子300上，从而减小振子300转动过程中的离心现象。
请再次参考图1～图3，一种可选的方案中，中框110可以包括中间段111和两个边缘段112，中间段111位于两个边缘段112之间，边缘段112的外侧表面与中间段111的外侧表面位于同一平面内，中间段111的壁厚大于边缘段112的壁厚。具体的，第一安装空间和第二安装空间均可以开设于中间段111，在此种情况下，第一安装空间和第二安装空间内可以布置较多的线圈，进而分别形成第三子线圈510和第四子线圈520，进而能够使得第三子线圈510和第四子线圈520在通电状态下形成更为强大的磁场，最终达到更好地驱动振子300转动的目的。而且，由于中间段111的壁厚较大，因此能够使得第三子线圈510与第三子磁体710的距离以及第四子线圈520与第四子磁体720的距离均较小，进而能够进一步提高相互之间的磁力，达到更好地驱动振子300转动的目的。
请再次参考图1～图3，在另一种可选的方案中，第一盖体120可以包括第一盖本体121和第一围挡122，第一围挡122固定在第一盖本体121的内侧表面，具体的，第一围挡122可以与第一盖本体121为一体式结构。第一盖本体121位于第一围挡122的外侧的部位可以与第一围挡122形成第一限位沉台，在安装的过程中，第一限位沉台能够与中框110的一个端口所在的表面限位配合，从而能够提高装配的稳定性，同时还方便支架100的快速组装。
具体地，第一子线圈410可以定位于第一围挡122围成的空间内，从而能够提高装配的稳定性。
同理，在又一种可选的方案中，第二盖体130可以包括第二盖本体131和第二围挡132，第二围挡132固定在第二盖本体131的内侧表面。具体地，第二围挡132可以与第二盖本体131为一体式结构。第二盖本体131位于第二围挡132的外侧的部位可以与第二围挡132形成第二限位沉台，在安装的过程中，第二限位沉台能够与中框110的另一个端口所在的表面限位配合，从而能够提高装配的稳定性。同时，还能方便支架100的快速组装。具体的，第二子线圈420可以定位于第二围挡132围成的空间内，从而能够提高装配的稳定性。
一种可选的方案中，振子300可以为筒状结构件，振子300可以套设在导向轴200上。振子300套设在导向轴200上，有利于使得振子300在转动的过程中对导向轴200施加的作用力较为均衡，避免导向轴200受力损坏。具体的，振子300可以通过轴承800与导向轴200配合，轴承800能够实现振子300沿着导向轴200的移动，也能实现振子300相对于导向轴200的转动。一种具体的实施方式中，轴承800的内圈可以套设在导向轴200上，进而与导向轴200在导向轴200的延伸方向滑动配合，轴承800的外圈可以固定于振子300的中心孔中，振子300能够通过外圈与内圈之间的滚动体，进而实现相对于导向轴200的转动，振子300能够通过轴承800沿导向轴200滑动。
当然，振子300不局限于通过轴承800实现与导向轴200的装配，具体的，振子300可以直接套设在导向轴200上，通过轴孔实现滑动及转动配合。具体的，振子300的中心孔的内壁与导向轴200之间可以形成间隙，进而实现振子300的活动设置。
一种具体的实施方式中，本发明实施例公开的第一子磁体610、第二子磁体620、第三子磁体710和第四子磁体720可以均为磁钢，当然还可以为其它种类的磁性件，本发明实施例对此不作限制。
